Twentieth Amendment to the United States Constitution

From Wikipedia, the free encyclopedia

The Twentieth Amendment (Amendment XX) to the United States Constitution moved the beginning and ending of the terms of the president and vice president from March 4 to January 20, and of members of Congress from March 4 to January 3. It also has provisions that determine what is to be done when there is no president-elect. The Twentieth Amendment was adopted on January 23, 1933.[1]

The amendment reduced the presidential transition and the "lame duck" period, by which members of Congress and the president serve the remainder of their terms after an election. The amendment established congressional terms to begin before presidential terms and that the incoming Congress, rather than the outgoing one, would hold a contingent election if the Electoral College deadlocked regarding either the presidential or vice presidential elections.



Section 1. The terms of the President and Vice President shall end at noon on the 20th day of January, and the terms of Senators and Representatives at noon on the 3d day of January, of the years in which such terms would have ended if this article had not been ratified; and the terms of their successors shall then begin.

Section 2. The Congress shall assemble at least once in every year, and such meeting shall begin at noon on the 3d day of January unless they shall by law appoint a different day.

Section 3. If, at the time fixed for the beginning of the term of the President, the President-elect shall have died, the Vice President-elect shall become President. If a President shall not have been chosen before the time fixed for the beginning of his term, or if the President-elect shall have failed to qualify, then the Vice President-elect shall act as President until a President shall have qualified; and the Congress may by law provide for the case wherein neither a President-elect nor a Vice President-elect shall have qualified, declaring who shall then act as President, or the manner in which one who is to act shall be selected, and such person shall act accordingly until a President or Vice President shall have qualified.

Section 4. The Congress may by law provide for the case of the death of any of the persons from whom the House of Representatives may choose a President whenever the right of choice shall have devolved upon them, and for the case of the death of any of the persons from whom the Senate may choose a Vice President whenever the right of choice shall have devolved upon them.

Section 5. Sections 1 and 2 shall take effect on the 15th day of October following the ratification of this article.

Section 6. This article shall be inoperative unless it shall have been ratified as an amendment to the Constitution by the legislatures of three-fourths of the several States within seven years from the date of its submission.

Historical background


Original text of the Constitution


Article I, Section 4, Clause 2 of the Constitution states that Congress must meet at least once a year. The default date specified is the first Monday in December, though Congress is empowered to set another date and the president can summon special sessions.

The original text of the Constitution set a duration for the terms of federal elected officials, but not the specific dates on which those terms would begin or end. In September 1788, after the necessary nine states had ratified the Constitution, the Congress of the Confederation set March 4, 1789, as the date "for commencing proceedings" of the newly reorganized government. Despite the fact that the new Congress and presidential administration did not begin operation until April, March 4 was deemed to be the beginning of the newly elected officials' terms of office, and thus of the terms of their successors.[2] The Constitution did not specify a date for federal elections, but by the time of the second presidential election in 1792, Congress had passed a law requiring presidential electors to be chosen during November or early December.[3] By 1845, this was narrowed to a single day, in early November.[4] Congressional elections were generally held on the same day.



The result of these scheduling decisions was that there was a long, four-month lame duck period between the election and inauguration of the new president. For Congress, the situation was perhaps even more awkward. Because Article I, Section 4, Clause 2 mandated a Congressional meeting every December, after the election but before Congressional terms of office had expired, a lame-duck session was required by the Constitution in even-numbered years; the next session was not required until the next December, meaning new members of Congress might not begin their work until more than a year after they had been elected. Special sessions sometimes met earlier in the year, but this never became a regular practice, despite the Constitution allowing for it. In practice, Congress usually met in a long session beginning in Decembers of odd-numbered years, and in a short lame-duck session in December of even-numbered years.[5]

The long lame-duck period might have been a practical necessity at the end of the 18th century, when any newly elected official might require several months to put his affairs in order and then undertake an arduous journey from his home to the national capital, but it eventually had the effect of impeding the functioning of government in the modern age. From the early 19th century, it also meant a lame-duck Congress and presidential administration would fail to adequately respond to a significant national crisis in a timely manner. Each institution could do this on the theory that, at best, a lame-duck Congress or administration had neither the time nor the mandate to tackle problems, whereas the incoming administration or Congress would have both the time and a fresh electoral mandate, to examine and address the problems the nation faced. These problems very likely would have been at the center of the debate of the just-completed election cycle.

This dilemma was seen most notably in 1861 and 1933, after the elections of Abraham Lincoln and Franklin D. Roosevelt, respectively, plus the newly elected Senators and Representatives. Under the Constitution at the time, these presidents had to wait four months before they and the incoming Congresses could deal with the secession of Southern states and the Great Depression respectively.

In 1916, during World War I, President Woodrow Wilson devised an unorthodox plan to avoid a lame-duck presidency and allow his Republican opponent Charles Evans Hughes to assume presidential powers immediately if Hughes had won the election. In that case, Wilson planned to appoint Hughes as Secretary of State, who under the Presidential Succession Act of 1886 was second in the presidential line of succession. President Wilson and Vice President Thomas R. Marshall would have then both resigned, leaving Hughes to become acting president. The plan was never implemented because Wilson was narrowly re-elected.[6]

Section 1 of the Twentieth Amendment prescribes that the start and end of the four-year term of both the president and vice president shall be at noon on January 20. The change superseded the Twelfth Amendment's reference to March 4 as the date by which the House of Representatives must—under circumstances where no candidate won an absolute majority of votes for president in the Electoral College—conduct a contingent presidential election.[9] The new date reduced the period between election day in November and Inauguration Day, the presidential transition, by about six weeks.[10] Section 1 also specifies noon January 3 as the start and end of the terms of members of the Senate and the House of Representatives; the previous date had also been March 4.[11]

Section 2 moves the yearly start date of congressional sessions from the first Monday in December, as mandated by Article I, Section 4, Clause 2, to noon on January 3 of the same year, though Congress still can by law set another date and the president can summon special sessions. This change eliminated the extended lame duck congressional sessions.[12] As a result of this change, if the Electoral College vote has not resulted in the election of either a president or vice president, the incoming Congress, as opposed to the outgoing one, would conduct a contingent election, following the process set out in the Twelfth Amendment.[9]

Section 3 further refines the Twelfth Amendment by declaring that if the president-elect dies before Inauguration Day, the vice president-elect will be sworn in as president on that day and serve for the full four-year term to which that person was elected. It further states that if, on Inauguration Day, a president-elect has not yet been chosen, or if the president-elect fails to qualify, the vice president-elect would become acting president on Inauguration Day until a president-elect is chosen or the president-elect qualifies; previously, the Constitution did not say what was to be done if the Electoral College attempted to elect a constitutionally unqualified person as president.

Section 3 also authorizes Congress to determine who should be acting president if a new president and vice president have not been chosen by Inauguration Day. Acting on this authority, Congress added "failure to qualify" as a possible condition for presidential succession in the Presidential Succession Act of 1947.[13][14] The Constitution previously had been silent on this point, and this lack of guidance nearly caused constitutional crises on two occasions: when the House of Representatives seemed unable to break the deadlocked election of 1800, and when Congress seemed unable to resolve the disputed election of 1876.[15][16]

Section 4 permits Congress to statutorily clarify what should occur if either the House of Representatives must elect the president, and one of the candidates from whom it may choose dies, or if the Senate must elect the vice president and one of the candidates from whom it may choose dies. Congress has never enacted such a statute.[14][17]

Effect on the terms of elected officials


On February 15, 1933, 23 days after the amendment was adopted, President-elect Roosevelt was the target of an assassination attempt by Giuseppe Zangara. While Roosevelt was not injured, had the attempt been successful, then Vice President-elect John Nance Garner would have become president on March 4, 1933, pursuant to Section 3.[15]

Section 5 delayed Sections 1 and 2 taking effect until the first October 15 following the amendment's ratification. As it was adopted on January 23, 1933, Section 1 shortened the terms of representatives elected to the 73rd Congress (1933–1935), as well as those of senators elected for terms ending in 1935, 1937, and 1939, by 60 days, by ending those terms on January 3 of each odd-numbered year rather than the March 4 date on which those terms originally were due to expire. Section 5 also resulted in the 73rd Congress not being required to meet until January 3, 1934.[18]

The first Congress to open its first session and begin its members' terms on the new date was the 74th Congress in 1935. The first presidential and vice presidential terms to begin on the date appointed by the Twentieth Amendment were the second terms of President Roosevelt and Vice President Garner, on January 20, 1937. As Section 1 had shortened the first term of both (1933–1937) by 43 days, Garner thus served as vice-president for two full terms, but he did not serve a full eight years: his vice presidency spanned from March 4, 1933, to January 20, 1941.
